Description

n VEHICLE SUSPENSION Background of the invention This patent application relates to the area of and specifically to trancport There are several ty pes of suspensions in the general these suspensions provide amortization of the frame of a torsion i suspensions and suspensions based on the use of different compression springs have a wide A choice from these types is determined according to requirements of proper the size of the posi tion in or out the frame of the the weight of a vehicl and i s is desired that a suspension roller will not be hung and will not lose contact with a track chain on its This is a new requirement in relation to a suspension and it allows to de crease the height of the tow hooks of a track this not only decreases its but generates other possibilities to improve operation properties of the It is an aim of this patent application to propose a suspension which provides a required characteristi s and at the same time it has a moderate it is situated outside of the vehicle between the top and lower run of a track chain and its production is not This suspension must provide contact of the track chain with rollers on sagging of the track when it is a suspension spring can be ded with a e chara teristi s at the end of the it is achieved by decreasing the number of spring which are actuated shown in The suspension of a road wheel of a the general view and the sectional view on the section are shown in A helical spring is used as an elastic element of the Hub 2 is situated on the horizontal axle which is immediately connected with the frame of the This hub is furnished with bracket 3 on its external one end of spring 4 is fastened in it by gusset The spring is designed with an angle of helix to and the rizontal component this angle of helix must be directed toward the The diameters ratio must be not less than Key 6 is positioned on the internal surface of hub The axial bearing 7 is fastened to the axle hub 2 is rested by its face plane upon this Hub 2 position on axle 1 is locked by pin There is the notch at the face plane of axle depth is equal to the length of the key and a width of the notch is determined by a required depth of falling roller 9 after sagging the track Hub 2 can be revolved freely on axle 1 within the boundaries of the notch The other end of the spring is connected by bracket 10 with the axle of the roller and with the roller The recti liniar end of the spring is serving as a balance During passage through a depression and the track chain sagging accompanied with the roller is lowering after the track chain at the cost of rotation of hub 2 in relation to axle 1 up to the stop of key 6 in the side wall of the During opposite movement of the track chain with the hub 2 revolves in opposite direction up to the stop of key 6 in the opposite wall of the notch and during further hoisting the roller the spring is functioning as an elastic insufficientOCRQuality
